Barcelona - BMW Sauber - Test day 3The BMW Sauber team once again concentrated on evaluation work with the F1.08B interim car in the final day of the Barcelona group test. Based on a 2008 chassis with some aerodynamic components complying with the 2009 regulations, the
two cars ran for 106 and 88 laps respectively.
Christian Klien again drove the car equipped with KERS, working on the setup of the system. Just before the end of the morning session he had a minor off caused by a hydraulic-related problem in the drivetrain. After repairs he was able to resume testing duties following the lunch break. Klien recorded the sixth fastest lap of the day on a 1:21.534.
Nick Heidfeld was at the wheel of the BMW Sauber F1.08B without KERS, working on reliability as well as trying different solutions for the mechanical and aerodynamic setup with the 2009 season in mind.
While getting used to the slick tyres he also had the chance to collect data on the all-new power-adjustable front wing. “Heidfeld was seventh fastest on a 1:21.592s best.
"Definitely the slick tyres provide more grip than the 2008 grooved tyres,"”Heidfeld said. "On the other hand we have to start from zero by learning how the slick tyres heat up and for how many laps they deliver optimum performance."
